1 Claim.

This invention is a device for facilitating the removal of screw capsfrom jars, and particularly for facilitating the removal of the threadedcap of Mason jars and the like.

An object of the invention is to provide a simple and easily operatedform of wrench particularly adapted for the purpose above mentioned, andwhich also includes as an integral part thereof a can opener and acrimped bottle cap remover.

The invention, together with its objects and advantages, will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is an upper side view in elevation of the improved form ofwrench.

Figure 2 is a perspective view thereof.

Figure 3 is a perspective view of the movable jaw of the wrench.

Figure 4 is a perspective view of a cam equippe lever.

Figure 5 is an end 'elavational view of the I wrench showing the sameapplied to a screw cap.

Figure 6 is a view similar to Figure 1 illustrating a slightly modifiedform of the invention.

Figure '7 is a perspective view of an end portion of a shank formingpart of the second form of ing a flat elongated shank It! provided atone end with a handle ll.

In the form of the invention shown in Figures 1 to 5 inclusive the shankID at the free end thereof has integral therewith a laterallyextending'jaw 52 that is in a plane offset to the plane of the shank illand is connected with the front of the shank by a narrow web l3 thatextends at right angles to the plane of the shank and is integral withthe shank l0 and the jaw l2. The

jaw I2 is slightly tapered and adjacent its free at one corner, areconnected together by a substantially U-shaped tooth 20 and at arelatively opposite corner and for a considerable part of the lengththereof are connected by an integral toothed jaw 2| (see Figure 3). Thetooth 20 of the slide I9 matches the teeth I! on the shank, whereby tohold the slide IS in the required ad justed position. The jaw 2l istoothed to match the teeth of the jaw l2 for clamping between said jawsthe screw cap of the jar.

A cam 22 formed integrally one one end of a handle or lever 23 ispivotally connected to the slide I9 as at 24 at the end of the slideequipped with the jaw 2|.

When the movable jaw, that is, the jaw 2| provided on the slide I9 is inlocked position, the parts assume the position shown, as for example inFigure l, the shank I! being held between the tooth 20 and the cam 22.When it is required to adjust the movable jaw 2|, the lever 23 isrotated in a direction outwardly or away from the shank l0 wherebyprovision is made for releasing the tooth 20 and permitting the slide tobe moved along the shank ID to adjust the jaw 2| to accommodate theparticular jar cap or work,

therewith are made secure by pressing the lever 23 inwardly to theposition shown in Figure 1 so that cam 22 and tooth 20 thus engage withthe shank ID in a manner to lock the slide l9 and the jaw 2| carriedthereby.

By having the jaw l2 offset from and parallel to the plane of the shankID, and the bottle cap remover [5 arranged substantially coplanar withthe shank I0 it will be seen that the shank I0 and the bottle capremover' l5 rest on top of the screw cap 24 that is to be removed fromthe jar 25 and with the toothed face of the jaw l2 engaging theperiphery of the cap 24, the

cap 24 thus provides a support for the jaw.

equipped end of the shank ID permitting quicker action on the part ofthe operator in adjusting the jaw 2| and the clamping thereof at therequired adjusted position.

The form of the invention shown in Figures 6 to 8 inclusive is used insubstantially the same manner as is the form of the invention shown inFigures 1 to 5 inclusive. However, in the second form of the invention,that is, in the form of the invention shown in Figures 6 to 8 inclusive,instead of having the fixed jaw integral with the shank, said jawindicated by the reference numeral I2 is integral with an attachingplate 26 in the same manner as the jaw I2 is integral with the shank I0.Also, the bottle cap remover after which the slide l8 and jaw 2iassociated I5 is integral with the jaw l2 in the same manner as is thebottle cap remover l5 integral with jaw l2. In the modified form of theinvention, the plate 26 is adapted to be secured to the free end of theshank ID by rivets or any other suitable fastening means 21, andintegral with the plate 26 at the edge thereof opposite to the jaw I2 isa can opener blade 28.

What is claimed is: Y

A wrench of the class describedcomprising an elongated shank havingteeth at its rear side, a stationary jaw connected at one end to thefront side of the shank, said jaw having a portion'in a plane offsetfrom the plane of the shank and having an inwardly extending projectionat the outer end thereof, lying substantially in the r shank and thebight of the movable jaw between the opening and the other end havingteeth thereon to cooperate with the'teeth on the firstmentionedj aw anda handle pivoted at said other end of the jaw between the flanges of thechannel and provided with a cam at its pivoted end for engaging thefront edge of the shank.
